SPECIFICATION forming part of Letters Patent No. 392,404, dated November 6. 1888.

Application filed November 10, 1887. Serial No. 255,611. (No model.)

To all whom, it may concern:

Be it known that I, OLIVER RBRADFOED, of Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Shoes; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it pertains to make and use the same.

My invention relates to shoes, and more particularly to shoes having the soles, heels, taps, legs, or other parts made of :lire-prooi' material.

It is well known that in rolling-mills, fouudries, furnaces, and like establishments the shoes of the workmen are frequently burned by the treading upon heated scraps of metal, Che.

The object of my invention is to provide a shoe for the purpose stated that will be efficient and durable.

In the accompanying drawings, FigureV 1 shows 'a shoe provided with a sole made of my improved fabric. Fig. 2is a cross-section of the shoesole.

instance, for making shoe taps or legs a lighter fabric would be used than for shoe soles or heels.

I do not limit myself to any particular configuration of wire-netting, nor to any specific method of shaping the material.

I also desire to have it understood that my invention eomprehends the use of any fireproof filling and is not restricted to the use of 45 asbestos, as many ire proof compositions could be used satisfactorily.

If desired, an entire foot-covering-such as a slipper or moccasin-might be made of my re-proof material, with a leg or leggins attached or detached.

In the drawings I have shown, for conven ience, only the sole of a shoe made in accordance with my invention; but it will be understood that I contemplate making the shoe either partially or wholly of said material, or any part desired.

Having fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is l 1. As an improved article of manufacture, an outer sole for boots or shoes comprising a wire frame presenting the configuration of the sole, and a filling of fire-proof material located within the interstices of the frame to form con- 6 5 tact-faces for the sole, substantially as set forth.

2. The combination, in a boot or shoe, of an outer sole comprising a wire frame presenting the configuration of the sole, and a filling of asbestus located within the interstices of the 7o frame to form contact-faces, substantially as set forth.

In testimony whereof I have signed thisspecification in the presence of two subscribing witnesses.

OLIVER B. BRADFORD.
